Virtual Reality technology is widely used in several domains. Recently evacuation experience using VR is expected to provide hi-fidelity where users are involved and can feel realistic situation than simply viewing image films. Hi fidelity is sufficient from image standpoints but not from balance loss standpoints. Since "vection stimulus " raises such balance loss internally, we propose shake motion generation method reflecting seismic waves towards VR special objects, which will achieve more realistic experience for earthquake evacuation training.
